383 Head Gasket Recomendations

I removed the top end of this engine today. It has true L2315 forged pistons, .030 over, and it looks like the pistons are about .010 in the hole. I am going to use a set of 906 heads I have that are uncut. Any idea of the compression ratio? I am hoping some of you experts weigh in. It’s going to be a low boost build, about 6-8 pounds, and I am hoping this setup will be a good one. I have not cc’d the heads, I have the setup to do so, but the valve on the beaker wants to leak instead of flow downwards into the combustion chamber.
